There are a lot of supplemental information in the Internet about private and protected methods in Ruby, and about the difference between them. But I found no info regarding practical usage of the protected ones. When and why could we need to use them in real world? Could one provide an example, please?

I would rather ask when you would want a `private` method. – sawa Mar 07 '16 at 15:04

@sawa private methods are commonly used – DreamWalker Mar 07 '16 at 15:06

A private method is internal to the implementation of a class, and it can only be called by other instance methods of the class or its subclasses. – DreamWalker Mar 07 '16 at 15:14

Nope. That is protected method. – sawa Mar 07 '16 at 15:15
